Donald Trump and Mark Cuban Have Twitter Feud Fit for Billionaires

Even billionaires have fights on Twitter. That's what we learned this week after Dallas Mavericks owner and entrepreneur Mark Cuban and real-estate mogul turned reality TV star Donald Trump traded 140-character punches.

Here's how it went down: Trump challenged President Barack Obama to release his college transcripts in exchange for $5 million, which Trump would then donate to a charity of the president's choice. Last week, Cuban offered to donate $1 million to superstorm Sandy relief if Trump would shave his trademark hair.

On Monday, the Donald went on the offensive, saying, "Only $1 million? Offer me real money and I'd consider it. Your team and networks lose so much money I doubt you have much left!" Trump even knocked Cuban's new reality show, "Shark Tank," saying it was "shoved to Friday evening" and that Friday is considered "dead television."

Cuban responded that he was "at a loss for words." This morning, however, both men joined Dallas sports radio station 1310 AM the Ticket to discuss the matter. Phew! So glad we got past that one.
